We've done exactly that with the Parka-DB system (soon to be released 
as an RDF triple store, pending some code fixes).  A paper describing 
this work which was deployed at Johns Hopkins Hospital was published 
as
  K. Stoffel and J. Hendler,
  Back-End technology for High Performance Knowledge Representation 
Systems, IEEE Intelligent Systems, May, 1999

a preprint version of the paper is available on the web at
